$135 million Houston battery storage facility breaks ground

coming soon

SMT Energy and CenterPoint Energy have partnered with utility infrastructure solutions provider Irby Construction Company to break ground on a 160 megawatt battery energy storage system (BESS) located in the Houston zone of the ERCOT market.

“We are proud to be underway and deliver this grid-strengthening project to Houston,” Kevin Midei, SVP of engineering, procurement and construction, at SMT Energy, said in a news release.

The BESS, SMT Houston IV, is expected to support grid stability, deliver fast-response power during peak demands and provide resiliency and renewable integration. The project is expected to be online by 2026 and store and dispatch enough electricity to power 8,800 homes in Texas annually.

SMT Energy is the project owner and developer, and CenterPoint Energy will serve as the interconnecting utility, integrating the system into Houston’s broader electrical network,” according to the companies. Irby Construction will serve as the engineering, procurement, and construction (EPC) contractor, and construction of the project is expected to be completed by July. On May 14, the companies broke ground with a ribbon-cutting ceremony to symbolize the start of the build.

“Projects like this demonstrate how collaboration and forward-thinking infrastructure come together to power a more resilient energy future,” Tony Gardner, SVP and chief customer officer at CenterPoint, said in a news release. “At CenterPoint, we recently completed nearly 90 percent of our overall grid resiliency improvements. This is one more action we are taking to build a more resilient and reliable grid to better serve our customers.”

In March, Colorado-based SMT Energy secured $135 million in funding for the SMT Houston IV, led by Macquarie and KeyBanc Capital Markets as joint lead arrangers. In 2023, SMT Energy and joint venture partner SUSI Partners announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.

In 2019, Irby began construction on the Manatee BESS site with Florida Power and Light (FPL), which was the world’s largest BESS project at the time. Irby has built over 30 BESS sites and has more than 20 currently under construction or contract.

Chevron CEO touts biofuels as part of its renewable energy efforts

Betting on biofuels

As Chevron Chairman and CEO Mike Wirth surveys the renewable energy landscape, he sees the most potential in biofuels.

At a recent WSJ CEO Council event, Wirth put a particular emphasis on biofuels—the most established form of renewable energy—among the mix of low-carbon energy sources. According to Biofuels International, Chevron operates nine biorefineries around the world.

Biofuels are made from fats and oils, such as canola oil, soybean oil and used cooking oil.

At Chevron’s renewable diesel plant in Geismar, Louisiana, a recent expansion boosted annual production by 278 percent — from 90 million gallons to 340 million gallons. To drive innovation in the low-carbon-fuels sector, Chevron opened a technology center this summer at its renewable energy campus in Ames, Iowa.

Across the board, Chevron has earmarked $8 billion to advance its low-carbon business by 2028.

In addition to biofuels, Chevron’s low-carbon strategy includes hydrogen, although Wirth said hydrogen “is proving to be very difficult” because “you’re fighting the laws of thermodynamics.”

Nonetheless, Chevron is heavily invested in the hydrogen market:

As for geothermal energy, Wirth said it shows “some real promise.” Chevron’s plans for this segment of the renewable energy industry include a 20-megawatt geothermal pilot project in Northern California, according to the California Community Choice Association. The project is part of an initiative that aims to eventually produce 600 megawatts of geothermal energy.

What about solar and wind power?

“We start with things where we have some reason to believe we can create shareholder value, where we’ve got skills and competency, so we didn’t go into wind or solar because we’re not a turbine manufacturer installing wind and solar,” he said in remarks reported by The Wall Street Journal.

In a September interview with The New York Times, Wirth touched on Chevron’s green energy capabilities.

“We are investing in new technologies, like hydrogen, carbon capture and storage, lithium and renewable fuels,” Wirth said. “They are growing fast but off a very small base. We need to do things that meet demand as it exists and then evolve as demand evolves.”

Houston robotics company partners with Marathon Petroleum to scale fleet

robot alliance

Houston- and Boston-based Square Robot Inc. has announced a partnership with downstream and midstream energy giant Marathon Petroleum Corp. (NYSE: MPC).

The partnership comes with an undisclosed amount of funding from Marathon, which Square Robot says will help "shape the design and development" of its submersible robotics platform and scale its fleet for nationwide tank inspections.

“Marathon’s partnership marks a major milestone in our mission to transform industrial tank inspection,” David Lamont, CEO of Square Robot, said in a news release. “They recognize the proven value of our robotic inspections—eliminating confined space entry, reducing the environmental impact, and delivering major cost efficiencies all while keeping tanks on-line and working. We’re excited to work together with such a great company to expand inspection capabilities and accelerate innovation across the industry.”

The company closed a $13 million series B last year. At the time of closing, Square Robot said it would put the funding toward international expansion in Europe and the Middle East.

Square Robot develops autonomous, submersible robots that are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments. Its newest tank inspection robot, known as the SR-3HT, became commercially available and certified to operate at a broader temperature range than previous models in the company's portfolio this fall.

The company was first founded in the Boston area in 2016 and launched its Houston office in 2019.
